    Avaliação das Barreiras ao Uso de IoT nos Testes de Segurança e de Envelhecimento no Setor de Telefonia Celular Aplicando o DEMATEL
    (Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) LIMA, Wellyngton Araújo; LEITE, Jandecy Cabral; http://lattes.cnpq.br/7279183940171317
    This study investigated the barriers that hinder the implementation of the Internet of Things (IoT) in the security and aging tests of the cellular telephony sector in the Manaus Industrial Complex, considering the transformative potential of IoT for process optimization, increased efficiency, and improved real-time monitoring. The research was motivated by the observation that despite the technological advances and promises associated with IoT, its adoption in this specific context has been limited by technical, regulatory, and structural barriers. A systematic literature review combined with the Decision Making Trial and Evaluation Laboratory (DEMATEL) method, supported by field experts, was conducted. The results revealed that the most influential barriers were the shortage of qualified professionals, lack of regulation, and integration complexity, while interoperability and technical standards appeared more as secondary consequences. Based on these findings, a conceptual framework was proposed, providing a clearer understanding of the existing challenges and offering strategic guidance for overcoming them.

    Desenvolvimento de um protótipo de gateway para coleta e transmissão de dados em sistemas de manuseamento de materiais - Gate Move 4.0
    (Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) AMARAL, Carlos Henrique; LEITE, Jandecy Cabral
    Currently, material handling systems are fundamental in industries such as manufacturing, logistics, and distribution, performing critical functions in the movement, storage, control, and protection of materials throughout production and distribution processes. With the advancement of digital technologies and the emergence of Industry 4.0, there is a growing need for more intelligent and interconnected systems capable of collecting and transmitting real-time data, thus improving operational efficiency and decision-making. The primary objective of this study was to develop a gateway prototype called Gate Move 4.0, designed to efficiently and reliably collect and transmit data in material handling systems. The methodology adopted for the development of Gate Move 4.0 was organized into several stages, including requirements analysis, selection of system architectures and communication protocols, and prototype development and validation. The study results showed that Gate Move 4.0 is a functional prototype, meeting the proposed objectives and demonstrating satisfactory performance under various operating conditions. The key findings include data collection efficiency, connectivity and flexibility, and a positive impact on operational efficiency. Thus, this research contributes to the evolution of these systems towards more intelligent and interconnected operations within the Industry 4.0 context.

    Controle online de eletroestática em processos produtivos: monitoramento e gerenciamento das pulseiras eletrostáticas por meio de dashboard
    (Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) FREITAS, Wellison Dias de; VIEIRA JUNIOR, Milton
    In the electronics manufacturing industry, controlling static electricity is crucial to ensure product precision and reliability. Static electricity can cause significant damage to sensitive electronic components, leading to product failures and financial losses. This work aimed to establish methods for controlling the operation of anti-static wristbands using Wi-Fi and IoT communication. Specifically, it sought to identify sources of static electricity, minimize or eliminate these sources, evaluate existing control methods, and propose connectivity-based solutions. The research is characterized as applied and qualitative, with an exploratory approach and an action-research method. Data collection was carried out using tracking forms, involving production line workers who use anti-static wristbands. The implementation of the monitoring system aimed to replace manual control with an automated solution, using a transmitter box to send data to a central dashboard, accessible via tablet. Equipment installation included configuring the anti-static wristbands, transmitter boxes, and monitoring system. Preliminary tests ensured connectivity and real-time data transmission. The functionality of the system was validated through tests with RFID and sensors, confirming the effectiveness of continuous wristband monitoring and the ability to detect issues in real-time. The system was compared with previous manual monitoring, showing a significant improvement, with 100% coverage and real-time monitoring, eliminating the need for manual checks and increasing safety and accuracy. Future work should include prolonged assessment of equipment durability, testing in different environments and sectors, exploration of additional technologies, detailed economic analysis, and continued user feedback collection. These suggestions aim to enhance the system and expand knowledge on static electricity control in the industry.
